KAME project

The KAME project was a joint effort of six organizations in Japan which aimed to provide a free IPv6 and IPsec (for both IPv4 and IPv6) protocol stack implementation for variants of the BSDUnix computer operating-system.[1] The project began in 1998 and on November 7, 2005 it was announced that the project would be finished at the end of March 2006.[2]The name KAME is a short version of Karigome, the location of the project's offices, and it also is a word for turtles.[3]

FreeBSD, NetBSD and DragonFly BSD integrated IPSec and IPv6 code from the KAME project; OpenBSD integrated just IPv6 code rather than both (having developed their own IPSec stack). Linux also integrated code from the project in its native IPsec implementation.[4]
